The Thing in My Mind

In the Third Multiverse, the year is 2075. Technology has stagnated for a long time. Without consulting the other nations, the country code-named M unilaterally sends Earth's coordinates and level information into space. On the surface, it exchanges technology with other civilizations, but in truth it seeks to expand through invasion. Yet extraterrestrial civilizations are no pushovers, and in 2100, a war of the century will erupt. I am a high school student, but an accident puts a low-level chip from a high civilization inside my mind. It helps me become the one who wields Earth's sword 25 years later, and stop the war before it begins. A creator from a level-seven civilization develops the chip in my brain to 80% of its potential. By digitizing the world's operating data, it helps me defy fate and change my destiny. In the end, I gain the ability to create a space, move instantly regardless of distance, and travel through time and space, becoming a new generation of god. I prepare to face the final battle of this century, but things behind the scenes seem far from simple.
